This field displays the identifying name of this certificate. If you want to change the
name, type up to 31 characters to identify this key certificate. You may use any
character (not including spaces).

Property
Check incoming
certificates issued by
this CA against a
CRL

Select this check box to have the ZyWALL check incoming certificates that are
issued by this certification authority against a Certificate Revocation List (CRL).

Certification Path

Click the Refresh button to have this read-only text box display the end entity’s
certificate and a list of certification authority certificates that shows the hierarchy of
certification authorities that validate the end entity’s certificate. If the issuing
certification authority is one that you have imported as a trusted certification
authority, it may be the only certification authority in the list (along with the end
entity’s own certificate). The ZyWALL does not trust the end entity’s certificate and
displays “Not trusted” in this field if any certificate on the path has expired or been
revoked.

Refresh

Click Refresh to display the certification path.

Certificate
Information

These read-only fields display detailed information about the certificate.

Type

This field displays general information about the certificate. “CA-signed” means
that a Certification Authority signed the certificate. “Self-signed” means that the
certificate’s owner signed the certificate (not a certification authority). “X.509”
means that this certificate was created and signed according to the ITU-T X.509
recommendation that defines the formats for public-key certificates.

Version

This field displays the X.509 version number.

Serial Number

This field displays the certificate’s identification number given by the certification
authority.

Subject

This field displays information that identifies the owner of the certificate, such as
Common Name (CN), Organizational Unit (OU), Organization (O) and Country (C).

Issuer

This field displays identifying information about the certificate’s issuing certification
authority, such as Common Name, Organizational Unit, Organization and Country.

With self-signed certificates, this is the same information as in the Subject Name
field.
